摘要

一个云掩模程序可以掩盖海岸观察卫星图像产品上的所有云。海岸观察卫星图像是NOAA极地卫星1公里高级甚高分辨率辐射计(AVHRR)的运行数据，这些数据是针对指定的美国沿海地区重新绘制的。海面温度图像是目前海岸观察的产品之一;然而，该产品包含浑浊像素。为了确定海面温度，必须使用云掩模产品来确定无云区域。AVHRR (CLAVR)云检测算法正在白天和夜间AVHRR图像上进行测试。本文介绍了云掩蔽试验的解释，并举例说明了它们在近实时基础上对美国沿海海面温度图像的分析

Cloud masking for CoastWatch satellite imagery

A cloud mask program is available for masking out all clouds present on CoastWatch satellite imagery products. CoastWatch satellite imagery are operational NOAA polar-satellite 1 km Advanced Very High Resolution Radiometer (AVHRR) data that are remapped for designated U.S. coastal regions. Sea surface temperature imagery is one of the current CoastWatch products; however, the product contains cloudy pixels. A cloud mask product is necessary to determine cloud free areas for sea surface temperature identification. The Clouds from AVHRR (CLAVR) cloud detection algorithm is being tested on both day and night AVHRR imagery. An explanation of the cloud masking tests and examples of their application to the analysis of sea surface temperature imagery for the coastal U.S. on a near-real time basis are presented.<>
